I just looked at my iGoogle page for the first time in probably two years. On there, I have widgets for Washington, DC weather, Fark's RSS, the Buddhist Thought of the Day, my daily horoscope, Reuter's Oddly Enough RSS, and Top Stories news.
I wish I'd made more use of that page. I need to fancy it up a bit. Some of those widgets are stale!
I've already talked up Pageflakes in a previous post. I think that site is awesome. I've used it for school research. Someone has probably put up a flake on your research topic, why reinvent the wheel? See what someone else has already dug up.
